St. Petersburg scientists are ready to introduce to the market a product — hydrogen fuel cells, which recognize the most promising alternative fuels for city vehicles. In parallel, the city does not forget about electricity as a harmless source of energy for cars — a month in the city will build a charging infrastructure for electric vehicles.
At the end of August in St. Petersburg are going to open the first charging station for electric vehicles — it will appear in one of the largest shopping malls in the city center. Petersburg so far behind in this respect from Moscow, where there are several dozen of these stations. Russia's first forum dedicated to electric transport and the charging infrastructure, held in July in Moscow. It promised that in the near future in St. Petersburg can create a whole network of charging until about negotiations with representatives of the business. And then these points will create in other major cities of the country.
If the charging infrastructure by private companies, the scientists are trying to develop more environmentally friendly sources of energy for cars, first of all, hydrogen cells, which environmentalists tipped a bright future in the field of transportation. The impact of this gas on the environment is minimal, which allowed to speak not just about hydrogen power, but about the hydrogen economy.
Since liquid hydrogen destroys metal engines, all developments in this area have focused on the creation of the hydrogen fuel cells, and one of the leading Russian developers began Petersburg scientists who said they are almost ready to introduce an element designed to market. Deputy General Director of the Central Research Institute of Electrical Engineering and Ship Technology Gennady Fists said that the fuel cell itself is ready, work remains to resource indicators.
We are soon going to bring a product to market, — the Fists — but so far, experience shows that the use of such vehicles for the fuel cell will be too expensive, and that it was cheaper, it is necessary to develop a series of such fuel cells. But, of course, is the fuel of the future.
According to the scientist, yet when entering the market makers of hydrogen fuel primarily rely on the scope of protection of gas pipelines — instead of extending power lines to thousands of miles away, you can create a gas-fired power plant. Needed to operate the hydrogen is taken out of gas, oxygen — in the air, and the exhaust is water vapor, which is perfectly safe for the environment. In the next two years, the St. Petersburg Institute will work to build a pilot plant for this type of "Gazprom" — fuel cell is, and a comprehensive system be set up. Head of research and educational programs of the Center diagnose and repair technology vehicles Konstantin Gavrilov believes that fuel cells will not soon be able to replace Russian gas for cars due to its high cost and a variety of difficulties in the handling of hydrogen.
For example, a mixture of gaseous hydrogen and oxygen in the air to form detonating gas, and fuel required for such special "afterburners" change motor insulation and cooling of hydrogen to a temperature at which it loses its explosive properties. In a fuel cell gas is off, and decomposes, feeding onboard power plant. The only drawback — you need a platinum membrane, making these engines are not only very expensive, but short-lived.
The cost of production, storage and conservation of hydrogen leads to the fact that the right to move a car is a small proportion of the power generation efficiency of compressed hydrogen internal combustion engine is 22 percent, liquid — 17 percent. This allows the skeptics to believe that hydrogen cells are unlikely in the near future the main element of the engine of the future.
By the way
One of the types of alternative motor fuel, which is actively used in St. Petersburg, is a gas. In the city and the Leningrad region already has about forty stations where you can fill the car with gas — methane, propane, butane, compressed natural gas. No support measures for car owners driving on gas, there is not yet used, but the number of filling stations is slowly but steadily growing. Several companies in providing services for the conversion of vehicles to natural gas. Now propane-butane gas stations costs about 14 cents per liter, butane — to 9 rubles per cubic meter, the price of various types of traditional gasoline range between 27-40 cents per liter.
